Indian conglomerate Adani Enterprises Ltd. will miss its original deadline to start shipping thermal coal from one of the world’s biggest planned mines due to funding difficulties, even as it eyes export deals with Asian companies.

GAIL India Ltd. received notification from Russia’s Gazprom PJSC that it plans to start deliveries of liquefied natural gas through a contract the Indian buyer is trying to renegotiate, according to people with knowledge of the matter.
